    • A method and system for routing network-based data arranged in frames is disclosed. A host processor analyzes transferred bursts of data and initiates an address and look up algorithm for dispatching the frame to a desired destination. A shared system memory existing between a network device, e.g., an HDLC controller, working in conjunction with the host processor, receives data, including any preselected address fields. The network device includes a plurality of ports. Each port includes a FIFO receive memory for receiving at least a first portion of a frame. The first portion of the frame includes data having the preselected address fields. A direct memory access unit transfers a burst of data from the FIFO receive memory to the shared system memory. A communications processor selects the amount of data to be transferred from the FIFO receive memory based on the desired address fields to be analyzed by the host processor.
    • 公开了一种用于路由布置在帧中的基于网络的数据的方法和系统。 主机处理器分析传输的数据突发,并发起一个地址和查找算法,用于将帧发送到所需的目的地。 存在于与主处理器结合工作的网络设备(例如,HDLC控制器)之间的共享系统存储器接收包括任何预先选择的地址字段的数据。 网络设备包括多个端口。 每个端口包括用于接收帧的至少第一部分的FIFO接收存储器。 帧的第一部分包括具有预选地址字段的数据。 直接存储器访问单元将数据从FIFO接收存储器传送到共享系统存储器。 通信处理器基于要由主处理器分析的期望的地址字段来选择要从FIFO接收存储器传送的数据量。
